Problems solved by technology

However, in the actual production and use process, the terminals of the liquid crystal display panel in the LCD are usually corroded
At present, people mainly use a microscope to manually identify and detect the terminals of the liquid crystal display panel in the LCD to avoid abnormalities in the LCD and LCM after assembly and use. Terminals cause damage, such as bumping terminals causing missing corners, electrostatic damage to terminals, etc.

Abstract

A device and method for detecting the corrosion state of a terminal. The device comprises a detection table (1) and a processor located in the detection table (1). The processor is separately and electrically connected a pH sensor (2) and a chloride ion content detector (3). The detection table (1) is used for controlling a terminal (4) to be tested to be in contact with gel (7). The pH sensor (2) is used for detecting the pH value of the gel (7) in contact with the terminal (4) to be tested. The chloride ion content detector (3) is used for detecting the chloride ion content of the gel (7) in contact with the terminal (4) to be tested. The processor is used for receiving the pH value and the chloride ion content value, and making comparative analysis between the pH value and a corresponding standard pH value and making comparative analysis between the chloride ion content value and a corresponding standard chloride ion content value.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a device and a method for detecting the corrosion state of a terminal. Background technique [0002] With the development of science and technology, LCD (Liquid Crystal Display, liquid crystal display) and LCM (LCD Module, LCD display module) are more and more used in the display field. In order to adapt to the rapid development of electronic products, people have higher and higher requirements on the performance status of the terminals of the liquid crystal display panel in the LCD. However, in the actual production and use process, the terminals of the liquid crystal display panel in the LCD usually have corrosion. At present, people mainly use a microscope to manually identify and detect the terminals of the liquid crystal display panel in the LCD to avoid abnormalities in the LCD and LCM after assembly and use. Damage to terminals, such as missing corners caused by bump...
